LOGO-L> circular spiral

[Paul C Dench <Paul.Dench@bigpond.com>]

Hello Megan

By the time you have all the suggestions you will be able to write a
dissertation on the subject so I hesitate to add to your 'confusion'

George Mills' solution is a very elegant 'growth solution but not very
transparent.

Yehuda's is too mathematical for my liking and even less transparent.


Marian Rosen's solution gets closer to the beginner Logo user thinking
progress and taken a step further we could think of quarter circles, eighth
circles etc or even smaller sectors as follows:

to spiral :size
repeat 500[fd :size rt 20 make "size :size + .2]
end

draw it by entering <spiral 1>

It's really no different than George's solution but easier to 'understand'.

Who'd have thought something as simple as a spiral would become an
epistemological issue.
